<10% of natural gas plants recover helium. All of them extract it. The remaining >90% vent it into the atmosphere. This is an engineering / money problem, not a physics problem.

It becomes a larger problem as the world moves away from fossil fuels like natural gas.
I'm not a chemist but are there really no alternatives? Running fusion plants to make helium seems very unlikely to become cost effective, but it would be quite the sci-fi future if we filled party balloons by bombarding hydrogen with free protons.
I guess there aren't any easy molecules to break apart to get helium either since its a noble gas. No hydrolyses type solutions because there aren't any molecules that incorporate helium. I guess radioactive decay, but even that is ultimately limited over long enough timescales.

So while you are right that nothing else stays liquid at those temps, we won’t be needing nearly as much helium in radiology in the next few years.

The article itself spells out several alternatives to buying continuous amounts of Helium: high temperature semiconductors and zero boil-off systems that don't require a continual supply.
All these "we're going to run out" stories pretend that engineering cannot adapt to changing cost structures, which is just total nonsense.
Sure, there is nothing that can be directly substituted for how we use Helium today, but clearly we're using Helium inefficiently today and the answer is that once markets force us to change, we will find more efficient ways.

generuso 19 hours ago [-]
There are many cases in the news of accidents with sometimes a large number of party balloons filled with hydrogen or other flammable gases.
One of the larger episodes was in 2012 in Armenia, where thousands of balloons exploded during a meeting, injuring 154 people, of which 4 seriously (the video is of poor quality): https://www.youtube.com/watch?v=jWEm2sS7Dw8
a party balloon - say a cubic foot - is about 2g of hydrogen. Involves 16g of oxygen. So we're talking 18g of very fast burning, borderline detonating mass. Releases 240 KJ of energy.
To compare the hand grenade - 60g TNT https://en.wikipedia.org/wiki/F-1_grenade_(Russia) - releases the same 240 KJ of energy.

summa_tech 7 hours ago [-]
While hydrogen-air mixes explode really readily (outstandingly wide flammability and pretty wide detonation range), and the energy released is considerable for the weight, the actual explosion does not produce a particularly high overpressure wave.
That's because the starting density of the hydrogen air mixes at near atmospheric pressure (such as in a balloon) is pretty low. Also, the balloon does not significantly contain the explosion, which reduces the danger a lot. I would not want to do it in a glass container.

Not like it was hard to get (and we had lots more interesting stuff than that in the lab, this was the 80s...). But the outcome I do remember.

As a kid I took a lot of classes at the Lawrence Hall of Science in Berkeley, which was paradise for fledgling nerds. On the last day they would have a little closing ceremony with some cute little science experiment. One of my favorites was "Going Out With A Bang".
The instructors would bring out a helium balloon and a candle on a meter stick. The balloon goes pop, huzzah.
Then the twist. "Hey, wanna do it again?" All the kids would be like "meh, I guess?" They would then bring out a balloon full of hydrogen (maybe some oxygen too?). It would look identical to the first one, floating there tethered to the lab bench.
When the candle hit the second one, it made a white flash and a really sharp BANG. It was an order of magnitude louder, and you could hear the transient bouncing off the walls and echoing in the halls. It made an impression.

I’m not really worried about any potential helium shortage. We are actually really good at extracting it, the problem is purely economics and as soon as prices get to the point where investment is warranted then there will continue to be adequate supplies. The main issue right now is the proper demand increase forecasts do not align with potential investments costs and helium extraction investment does just not make much economic sense given current forecast Helium costs.
vlovich123 1 days ago [-]
If demand keeps growing (as it has been), we've got ~40-60 years of "cheap" reserves left. As helium prices start to increase, you've got price shocks down the supply chain.
There's about 40-70 billion cubic meters of economically recoverable (assuming future technology development + price increases). The complete total upper end of known geological reserves is ~60-100 billion cubic meters - that's about correct in terms of order of magnitude even if we find new deposits.
Current consumption is 180 million cubic meters/year. At a growth of 3%, you've got 80-140 years before we run out. At 5% growth it's 50-90 years.
Saying "I'm not worried about it" is true in the myopically selfish "I personally won't have to care about it". It's conceivable that your children will be dealing with it and definitely grandchildren in a very real existentially meaningful way.

It's very hard if not impossible to do predictions over century timescales. How relevant are 1926 resource problems to today? If you wrote your comment in 1926 you would be talking about rubber, fertilizer, coal, wood or oil, and 4 out of those 5 are mostly solved today.
At those timescales, mining the moon or Jupiter for helium might be realistic, so the limits of earth are no longer upper bounds.
pureliquidhw 1 days ago [-]
I agree century timescales are tough, I'm not convinced 4 of 5 of your listed things have been solved.
Rubber has been replaced with oil.
Fertilizer has been replaced with Natural Gas that comes from the same place as oil.
Coal usage has been replaced/displaced primarily by natural gas, see above.
Wood, or deforestation, was a real problem in the 1920's, but many uses were replaced by plastics (oil) and natural gas. Sustainable forestry helped a ton here too once it hit the paper industry's bottom line.
Oil is certainly not solved, so we solved 4 out of 5 with the 5th.
achierius 1 days ago [-]
Exactly -- that means that any analysis based on the current (as of 1926) 'reserves' or 'production capacity' for rubber/fertilizer/coal/wood would have been invalidated as soon as we switched to using oil instead. Imagine if instead of harvesting helium directly we find an economic way to split nitrogen (somehow, who knows). At that point, what you'd have to have forecasted would be the 'reserves' of nitrogen, which are functionally infinite.
vlovich123 17 hours ago [-]
That still amounts to magical thinking. And the point of the post that you’re replying to is that we didn’t actually make things better. We actually accelerated our exploitation of other resources to make up for the shortage of the others which had serious other negative side effects.
Since we’re dealing in magical hypotheticals, what if this new economical way to split nitrogen generated so much pollution that it poisoned natural water supplies? Also the “economic way” is misleading. If prices shoot up enough, then crazy things become economical like missions to other planets to retrieve it. But that’s an insane cost that has to be borne out by all humanity. Historically that worked because you increased how many people were on earth so it spread the cost out. However, it’s pretty clear the Earth is at carrying capacity for humans with our current technology which is why the population growth has slowed drastically. So increasing costs threaten to become a weight the next generation can’t lift resulting in societal collapse.

> Imagine if instead of harvesting helium directly we find an economic way to split nitrogen (somehow, who knows).
This is nonsense, from the physics point of view.
The reason why rubber/fertilizer were replaced by oil/gas products is that
oil/gas has the energy needed for the (relatively simple) chemical transformations needed to obtain rubber/fertilizer from the feedstocks.
Splitting nitrogen into helium is a nuclear reaction that requires copious amounts of energy.
At least using fusion or collecting helium from Moon/Jupiter are physically sane, if economically insane.

For diving, there has been some experimental use of hydrogen as a partial replacement for helium in breathing gas mixtures. This obviously increases the risk of fires and the physiological effects aren't fully understood. But it might eventually be used in commercial, military, and exploration diving for those cases where we need to send humans really deep and using an atmospheric suit isn't an option. Regular sport divers will probably never breathe hydrogen.
For divers, we really should be focusing on building better underwater drones. Remove the risk to human life entirely. You don't need AI either, just a remote-controlled machine with a cable that goes up to the surface. I know there is some loss in dexterity with current robot arms, but building more dexterous system seems like it's not an impossible task.

ROVs have already reduced the demand for commercial divers on some types of work. But it's going to take decades (if ever) until they're able to do the full range of human tasks.

I really enjoyed this oddlots podcast episode that covered similar points and had a lot of "wat" moments for me, including the US selling off its strategic helium reserves at a loss because politicians labeled it "party baloon reserve", and how long it takes to produce naturally and how hard it is to find, process and transport.
To be fair, the decision to get sell off the strategic helium reserve wasn't a single point in time, it happened little by little, and the original idea came at a time when helium didn't really have a strategic purpose. The last major use for it was military spy balloons sent over western europe to keep tabs on the USSR... Yeah that USSR. They couldn't have anticipated that it would suddenly become ultra-useful for post-2010 semiconductor lithography.
parineum 1 days ago [-]
Part of the reason there's a shortage is because the US was the main supplier. There was no market incentive for anyone to invest into helium extraction.
It'd be like if the US used it's strategic oil reserve to supply the US with oil at a low price at all times.
A strategic reserve isn't supposed to be used as a supply. The existence of a strategic reserve shouldn't have an effect on the supply of helium except in an emergency. The fact that selling the helium reserve could create a shortage should tell you that it wasn't being used as a reserve but as a supply.
The US was, essentially, artificial subsidizing the price of helium. What's happening now is that people are actually paying the real price of helium.
marcosdumay 1 days ago [-]
The US government decided (maybe correctly, IDK) some years ago that their strategic helium reserves were too high (and thus expensive).
There were several announcements, a lot of discussion, and a long process before they started selling it. It was also a temporary action, with a well known end-date (that TBH, I never looked at). It had a known and constant small pressure over investments, it wasn't something that destabilized a market.

At the same time, such a revamp is desperately needed - the issues with the status quo are reeking - and everyone knows that it is highly, highly unlikely to get that done by ordinary democratic means due to the sheer inertia of hundreds of years of fossilized bureaucracy and individual/party interests.
And that is why so many people tend to vote for whoever shouts "destroy the country" the loudest - and not just in the US (MAGA) or UK ("Reform"), but also in Germany (AfD), Spain (Vox) or Italy (Salvini/Meloni), where economic inequality and perspectivelessness has hit absurd levels. Let it all burn to ashes, burn everything, even if one goes down with the fire, eat the rich, and try to build something more sane this time.

I usually get downvoted when I make an observation along these lines, but I will go for it again -- IMO some of the reason Europe has pulled ahead in infrastructure and policy is because a couple world wars last century reduced much of it to rubble, including the systems of governance. The UK mostly escaped that, and the US escaped nearly all of it. Which is one reason we can still have a lot of old electrical infrastructure, for example, that is pushing 100 years old, and a Constitutional system 250 years old.
I think a major problem with the system in the US is the difficulty changing it. There is a balance, and a lot of room for differing opinions on how flexible it really ought to be, but I suspect there is broad agreement that it is too inflexible. We rely too much on changing interpretations rather than changing the fundamentals.
Perhaps we really do need to risk a second Constitutional Convention. Or we will end up with a worse alternative.

I love my country quite literally to death. Death plays a strong role in the concept of freedom in American philosophy: Give me liberty, or give me death (yes, I know the real context of this quote), etc.
And so when my government wants to destroy my country, its land and its people, divide us, commodify us and our life experiences, and also export this kind of systematic industrial exploitation across the world, through colonies and coups and political assassinations; yeah, I hate that government a lot. I hate it to death. The American government has been an enemy to America, and an enemy to Americans. Since the beginning, with our treatment of the natives.
You'd do well to separate the land, people and government of a nation; confusing them only further serves State propaganda. We force children to say a pledge to our country in school, but it's really to our government. It's political brainwashing. I have refused to say the pledge since becoming politically aware enough around age 7. I cannot tersely express the amount of institutional abuse I suffered for this position. Teachers would ostracize me, bully me, punish me, attempt to physically force me to say it, write me up for detention, get my guardians to abuse me at home over it, etc. Like I said, the American government is a psyop.

observe that where Helium becomes a significant percentage, there is also Hydrogen and (monoatomic) Oxygen.
if one were driven by purism or vanity for stoichiometric exactness, then at a height of 1000 km theres 2 Hydrogens per Oxygen atom, so this could be reacted to water, and the energy used to power compression of the Helium, the water would freeze.
without this vanity, helium becomes a significant fraction at much lower heights... and thus higher densities.
The energy to compress becomes nearly insignificant at low pressures.

The overall amount of helium in the atmosphere is still more than enough for the foreseeable future, and it could be extracted (albeit at high energy cost) by augmenting existing air separation units (ASU's). Of course natural gas wells currently provide an easier to extract source, seeing as the concentration there is way higher.
nradov 24 hours ago [-]
Helium is only 5ppm in the atmosphere. Extracting useful quantities of it that way will probably never be economically viable.

MRI could switch to LH2. Yes, it's explosive and higher boiling temperature so would not support as high field and incompatible with currently used semiconductors. But it's doable. Plenty of other important uses (i. e. semiconductors and lasers) where it is much more irreplaceable.
miduil 9 hours ago [-]
New MRI only use 7 Liters (25 Cups) instead of ~1500L (~330Gallons) of liquid Helium due to better sealed magnets.
We are already separating out the majority elements from air via ASU plants, so we should compare the abundance of helium in what is left from typical extraction. And that looks quite technically viable, if obviously uneconomic at present.
ted_dunning 21 hours ago [-]
This is a very good point.
Oxygen, nitrogen, CO2 and argon make up 99.94% of the atmosphere. The remaining 0.06% has 5ppm is nearly 1% helium. That's up 200x from the original concentration and is well above the 0.3% that is sometimes quoted as the limit for economic extraction of helium (and well below the 7% of some natural gas).
Furthermore, the leftover gas is also already cold. It is absolutely true that 85K isn't very close to the boiling point of helium, it is a lot closer than starting at the temperature of gas at the well head.
The gotcha is almost certainly going to be that an ASU probably doesn't liquify most of the gas it takes in. That means that the exhaust gas will only be slightly enhanced.

Awesome graph! Worth stating that the increase in the relative fraction of He isn't so much because there's a lot of He out there as because there's a lot less of everything else. Overall density falls off roughly exponentially but lighter elements have a longer tail.
So once you get out to a few earth radii quite a bit of what you see might be ionized helium but that doesn't mean you can do much with it.

eddythompson80 17 hours ago [-]
That’s not true though. Helium doesn’t just rise through the atmosphere and gets lost to space. A helium balloon rises because it’s less dense than air, so air pushes up on it. It rises until the atmosphere is thin enough and stops there. When helium is not in a balloon, it doesn’t rise because it mixes with air and air doesn’t push on it. The atoms are still smaller and move faster than other gases. Some will go up and eventually gain enough speed to hit escape velocity. According to Maxwell-Boltzmann speed distribution of noble gases, only a small fraction of helium should be escaping the earth atmosphere due to that. The actual amount escaping is larger than predicted, but the exact mechanism isn’t fully agreed upon. Solar winds are thought to be responsible, but that’s just one theory. But the important thing is that helium doesn’t just rise when mixed with oxygen or nitrogen a.k.a “air”

Helium is produced naturally by radioactive decay underground. There is no way to artificially produce it in useful quantities.

Helium exists in great quantities in the 4 big planets, which unlike Earth have strong enough gravity to retain it.
Others have mentioned that some helium exists on the Moon, where it comes from the solar wind. The use of the helium 3 from there has been suggested for nuclear fusion, if the fusion of helium 3 became possible (it is much more difficult than the fusion of tritium with deuterium, which is the main approach attempted for now).
However, for fusion relatively small amounts could still be useful. For other uses the amount of lunar helium might not be enough, even when ignoring how expensive it would be to transport it from there.

And that's where all of our helium actually comes from. Any radioactive decay that emits alpha particles generates helium, since alpha particles are just helium nuclei. When that happens underground, the helium can get trapped. It tends to get trapped in the same places that natural gas gets trapped, so natural gas extraction often encounters helium as well.
Similar to oil and gas (although a completely different mechanism), it takes deep time to accumulate, but can be extracted much, much faster. So although new helium is being generated underground all the time, we can still run out in a practical sense.

wat10000 1 days ago [-]
I'd say no, although the amount of helium that's produced is small enough that it's not quite as absurd as I would have thought. Worldwide helium production is something around 25,000 tons/year. A nuclear power plant produces about 25 tons of waste per year. There are about 440 nuclear power plants in the world. If their waste consisted entirely of helium, that would be roughly 44% of total world helium production. More than I guessed! But, of course, only a tiny, tiny, tiny fraction of that waste ever turns into helium, so even if you somehow made it decay all at once, it would be be pretty insignificant on a world scale.
jmyeet 1 days ago [-]
Terrestial helium isn't produced by nuclear fusion. It's produced by nuclear decay. As you may know, you get alpha, beta and gamma radiation from decay. Gamma rays are just energetic photos. You typically need thick lead and/or concrete to shield you from them. Beta radiation is high energy electrons. A thin sheet of steel will shield you from those.
And lastly we have alpha radiation, which is just a Helium nucleus. A sheet of paper will generally block alpha radiation.
Some materials are really strong alpha emitters. A good example is Polonium-210 where almost all of its energy from decay is in the form of alpha radiation. This is why Po-210 is so lethal when ingested, which has been used for that purpose [1].
But this means if you produce a lump of Polonium-210, it's basically radiating Helium. The source of almost all of the Earth's Helium is from uranium and thorium decay.
They are indeed. The average planet busting Gamma Ray Burst is just a Vogon trying to "get the whole family in".

It's also formed similarly to oil over millions of years underground if I understand correctly so can be a byproduct of natural gas mining.
daemonologist 1 days ago [-]
It's often found alongside natural gas because the rock structures that can trap methane can also trap other gasses, but the original source is different - thermal decomposition of organic matter for natural gas and radioactive decay, mostly of uranium and thorium, for helium.
I agree that the "accumulation over millions of years" is similar (and similarly a potential problem if we burn through all that accumulation).
fraserphysics 22 hours ago [-]
Helium will leak out of some structures that hold methane. Shale will trap methane and let helium escape. Layers of salt trap both. Thus horizontal drilling and fracking to recover oil and methane from shale produces very little helium.

Which is exactly 100% of Earth's helium. Every single helium atom we use is a result of alpha decay, as a very good approximation there isn't any primordial or stellar helium on or in Earth.

The reason helium can't be produced chemically (like hydrogen can be produced e.g. from water) is that there are no natural chemical compounds which contain helium. That's because it doesn't form those compounds in the first place, since it's a noble gas.

If you have something that emits a lot of alpha particles as it decays, you could surround it with a source of electrons, I suppose. The details would have to be left as an exercise, and I doubt you'd get enough helium to be very useful unless you were dealing with large amounts of ridiculously-radioactive substances.
Same with fusion. Due to the implications of E=mc^2, fusion yields a lot of energy and a uselessly-small amount of matter. There don't seem to be many good ways to get a lot of helium besides either waiting millions of years for it to show up naturally, or carefully recycling what we already have.

Recently had to deal with radon in a basement, leading me to a fun side trek of learning about uranium decay (it has been a lot of years since chemistry classes).
When you hear about alpha decay of radioactive materials, that is the matter spitting off a highly ionized helium nucleus, freshly birthed into this world. That He nucleus rapidly steals electrons from matter, which is how it can be dangerous to human cells if ingested.
All of that helium underground is the result of alpha decay, and a single uranium-238 element will birth 8 helium atoms as it transitions through a series of metals and one gas (radon), then finally finding stability as Pb206. U235 will birth 7, becoming Pb207.
Anyways, found that fascinating. It's just happenstance that helium often gets blocked exiting the crust by the same sort of structures that block natural gas from escaping, and they are an odd-couple sharing little in common.
One other fun fact -- radon only has a half life of 3.8 days. Uranium becomes thorium becomes radium, then radon where it has an average 3.8 days to seep out of the Earth and into our basements, where it then becomes radioactive metals that attach to dust, get breathed in (or eaten) and present dangers. In the scale of things, crazy. Chemistry is fascinating.

The particle that is emitted from an alpha decay isn't actually called a He atom (I edited my root comment so this isn't misleading, apologies) -- I was being loose with terminology -- though it has the right number of protons and neutrons. It's called an alpha particle. Once it steals two electrons -- it carries a +2 charge and is extremely successfully at slicing electrons off of other molecules it comes across -- it is then considered the helium that we know and love, and is now stable with the properties we know.
And by stealing those electrons from other molecules it sets off other chemical reactions, which in things like DNA is highly suboptimal. This all generally happens at the birth of the He atom, presuming it isn't in deep space or something with no electrons to cleave from neighbours, and is only an instantaneous state.

>The vast majority of MRI machines used today use superconducting magnets made from niobium-titanium (NbTi), which becomes superconducting at 9.2 degrees above absolute zero. This is well below the boiling point of any other coolant, making liquid helium the only practical option for cooling the magnets.
Well, this is part of it. The other issue is that the superconducting phase diagram has two limits: the transition temperature Tc and the upper critical magnetic field Hc. The magnetic field limit is generally highest at absolute zero and drops steeply with temperature. Even for the superconductors with Tc as high as 120 K the Hc at 20 K will be much less than the Hc at 4 K. So in order to make powerful superconducting magnets you need helium regardless of what superconductor you use, since nothing has broken this pattern.

The US used to have a massive Strategic Helium Reserve [1]. Starting in the 1990s, Congress passed a law to sell down the reserve. This flooded the market with cheap Helium (yay, party balloons?) because the mandated pricing just didn't make any sense.
10-20 years ago there was a lot of talk about how this was foolish because it was depleting and squandering an unrenewable resource. But the thinking has shifted on that because it's an inevitable byproduct of natural gas production.
Now natural gas itself is limited but you can still get Helium from alpha decay of radioactive elements. Some elements are particularly strong alpha emitters (eg Polonium-210, Radium-223). They're basiclaly producing Helium constantly.
Helium is a known issue in various industries. The article notes (correctly) that MRI Helium use is decreasing because of the rise of so-called "Helium free" or "Helium light" MRI technology.
But there are short term supply issues. As noted, Qatar produces ~30% of the world's Helium currently. And that can (and has) been disrupted by recent events.
Lithography is a particularly important consumer of Helium for superconducting magnets. That demand is rising with probably no end in sight. Lithography itself is on the cutting edge of technology and engineering so seems harder to replace. I mean, EUV lithography is basically magic.
Shutting down the National Helium Reserve seemed like a good idea at the time. It was originally established when airships were considered essential for national security, largely for maritime patrol. But blimps and dirigibles fell out of favor for most military missions and there wasn't much demand for other uses, so it was politically hard to justify wasting tax dollars to maintain a reserve.

You'd need investors willing to pay $50,000\kg of helium, for one.
I'm not a chemist but are there really no alternatives? Running fusion plants to make helium seems very unlikely to become cost effective, but it would be quite the sci-fi future if we filled party balloons by bombarding hydrogen with free protons.
I guess there aren't any easy molecules to break apart to get helium either since its a noble gas. No hydrolyses type solutions because there aren't any molecules that incorporate helium. I guess radioactive decay, but even that is ultimately limited over long enough timescales.
We use a lot in our MR scanners.
The tech is changing and magnets are using far far less.
Super-conduction at higher temperatures has made progress too.
So while you are right that nothing else stays liquid at those temps, we won’t be needing nearly as much helium in radiology in the next few years.
The new generation use something like 700ml of helium, where the standard was hundreds of litres. https://magneticsmag.com/siemens-healthineers-gets-fda-clear...
How many loans for MRI machines that require helium haven't been paid back yet?
All these "we're going to run out" stories pretend that engineering cannot adapt to changing cost structures, which is just total nonsense.
Sure, there is nothing that can be directly substituted for how we use Helium today, but clearly we're using Helium inefficiently today and the answer is that once markets force us to change, we will find more efficient ways.
How dangerous are party balloons filled with hydrogen? Not a whole balloon arch obviously.
One of the larger episodes was in 2012 in Armenia, where thousands of balloons exploded during a meeting, injuring 154 people, of which 4 seriously (the video is of poor quality): https://www.youtube.com/watch?v=jWEm2sS7Dw8
A smaller, more recent episode in India: https://www.youtube.com/watch?v=FH5JwHeKnZo
That's because the starting density of the hydrogen air mixes at near atmospheric pressure (such as in a balloon) is pretty low. Also, the balloon does not significantly contain the explosion, which reduces the danger a lot. I would not want to do it in a glass container.
Things can always go wrong. We probably shouldn't strive for 100% safety because they we'd spend our lives in a padded cell. But we also shouldn't assume things are safe because they're common or routine.
https://en.wikipedia.org/wiki/Triple-alpha_process
I would.
How does that bang compare to the bang from an equally-inflated balloon full of ordinary air?
https://www.youtube.com/watch?v=Rwbyl7ywfhk&list=PLLnAFJxOjz...
Hydrogen mixed with air or with oxygen produces an ear piercing supersonic detonation, exceedingly loud and unpleasant. Not recommended for demonstrations.
ETA: I may be misremembering, the more I think about it, the more I recall that we did not use air, we did use pure oxygen. Not like it was hard to get (and we had lots more interesting stuff than that in the lab, this was the 80s...). But the outcome I do remember. The entire point of the experiment was to examine the difference between the individual pure elements and the mix. We expected the pure hydrogen to be far more interesting than it turned out.
The instructors would bring out a helium balloon and a candle on a meter stick. The balloon goes pop, huzzah.
Then the twist. "Hey, wanna do it again?" All the kids would be like "meh, I guess?" They would then bring out a balloon full of hydrogen (maybe some oxygen too?). It would look identical to the first one, floating there tethered to the lab bench.
When the candle hit the second one, it made a white flash and a really sharp BANG. It was an order of magnitude louder, and you could hear the transient bouncing off the walls and echoing in the halls. It made an impression.
I actually remember a similar problem from some compound that was mainly formed as a byproduct of some old Canadian nuclear reactor design. As the tech gets phased out, the material is no longer available in significant quantities, with consequences for a projects that need it (like Iter).
Some things can be cheap if they are produced as a byproduct, but very expensive if they have to be obtained directly.
There's about 40-70 billion cubic meters of economically recoverable (assuming future technology development + price increases). The complete total upper end of known geological reserves is ~60-100 billion cubic meters - that's about correct in terms of order of magnitude even if we find new deposits.
Current consumption is 180 million cubic meters/year. At a growth of 3%, you've got 80-140 years before we run out. At 5% growth it's 50-90 years.
Saying "I'm not worried about it" is true in the myopically selfish "I personally won't have to care about it". It's conceivable that your children will be dealing with it and definitely grandchildren in a very real existentially meaningful way.
At those timescales, mining the moon or Jupiter for helium might be realistic, so the limits of earth are no longer upper bounds.
Rubber has been replaced with oil.
Fertilizer has been replaced with Natural Gas that comes from the same place as oil.
Coal usage has been replaced/displaced primarily by natural gas, see above.
Wood, or deforestation, was a real problem in the 1920's, but many uses were replaced by plastics (oil) and natural gas. Sustainable forestry helped a ton here too once it hit the paper industry's bottom line.
Oil is certainly not solved, so we solved 4 out of 5 with the 5th.
Since we’re dealing in magical hypotheticals, what if this new economical way to split nitrogen generated so much pollution that it poisoned natural water supplies? Also the “economic way” is misleading. If prices shoot up enough, then crazy things become economical like missions to other planets to retrieve it. But that’s an insane cost that has to be borne out by all humanity. Historically that worked because you increased how many people were on earth so it spread the cost out. However, it’s pretty clear the Earth is at carrying capacity for humans with our current technology which is why the population growth has slowed drastically. So increasing costs threaten to become a weight the next generation can’t lift resulting in societal collapse.
This is nonsense, from the physics point of view.
The reason why rubber/fertilizer were replaced by oil/gas products is that oil/gas has the energy needed for the (relatively simple) chemical transformations needed to obtain rubber/fertilizer from the feedstocks.
Splitting nitrogen into helium is a nuclear reaction that requires copious amounts of energy.
At least using fusion or collecting helium from Moon/Jupiter are physically sane, if economically insane.
No shock at all if the price is relative to what's left. Shouldn't boring market pressures guarantee this, unless the government gets involved?
A standard western personality trait I’ve been confronted with repeatedly over the last… hmm. Well that got depressing real quick.

It'd be like if the US used it's strategic oil reserve to supply the US with oil at a low price at all times.
A strategic reserve isn't supposed to be used as a supply. The existence of a strategic reserve shouldn't have an effect on the supply of helium except in an emergency. The fact that selling the helium reserve could create a shortage should tell you that it wasn't being used as a reserve but as a supply.
The US was, essentially, artificial subsidizing the price of helium. What's happening now is that people are actually paying the real price of helium.
There were several announcements, a lot of discussion, and a long process before they started selling it. It was also a temporary action, with a well known end-date (that TBH, I never looked at). It had a known and constant small pressure over investments, it wasn't something that destabilized a market.
[1] https://www.tshaonline.org/handbook/entries/bush-dome-reserv...
Basically political bike shedding so elected officials could avoid making any hard or controversial decisions that would have a material impact but maybe upset some folks due to raising taxes or reducing spending.
A strategic petroleum reserve makes a lot of sense, petroleum is part of the food supply chain and it'd be stupid to be in a position where a short disruption could cause people to starve. Not to mention the military implications if an army can't zoom around because the petrol stations run dry for whatever reason.
I don't see anything on the list of uses for helium that looks particularly time- and helium- sensitive in the way that a strategic stockpile would help with.
I'm not seeing any need for a strategic reserve here. There aren't any strategic issues. It is a bit far-fetched that a helium shock will even lead to the end of MRIs.
Is there a widely-accepted definition of "an emergency" in the context of strategic reserves?
[Thinking of the SPR] "Oil/gas prices are currently higher due to geopolitical events, my [potential] voters are getting increasingly unhappy, and there is an election soon" would probably constitute an "an emergency" in the mind of a typical politician and his/her advisors.
Whether eg the SPR was created to (indirectly) help politicians keep their jobs is debatable.
The reserves are there to soften any quick price spikes or avoid them entirely, they aren't there to set the price in the long term. To my knowledge, the oil reserve has generally been used that way, even when the price change is self inflicted.
If they're not paying for the negative externalities that come from the methane extraction that comes along with it they really aren't paying the real price at all.
Apparently the regime is quite serious about the US being the actual devil.

The Iranians have been pragmatic and relatively restrained, while USA and Israel have repeatedly escalated.

1. While approaching the land, the Amalekites had attacked them, preying on the weak. God had said that they would be destroyed. Now, probably partly as a test for their first king (he failed, didn’t eradicate them), God said, get on and do it.
2. God had promised the land to Abraham and his descendants, but said they’d only get it in four hundred years’ time, because “the iniquity of the Amorites is not yet complete”—they still had time to choose God’s ways. Only once they were irredeemable were they to be destroyed.

That's because the US (and the UK) are about the only countries in this world that haven't had the entirety of their legal, economical and political system completely revamped at least once in the last 100 years - most countries average more than that.
At the same time, such a revamp is desperately needed - the issues with the status quo are reeking - and everyone knows that it is highly, highly unlikely to get that done by ordinary democratic means due to the sheer inertia of hundreds of years of fossilized bureaucracy and individual/party interests.
And that is why so many people tend to vote for whoever shouts "destroy the country" the loudest - and not just in the US (MAGA) or UK ("Reform"), but also in Germany (AfD), Spain (Vox) or Italy (Salvini/Meloni), where economic inequality and perspectivelessness has hit absurd levels. Let it all burn to ashes, burn everything, even if one goes down with the fire, eat the rich, and try to build something more sane this time.
I usually get downvoted when I make an observation along these lines, but I will go for it again -- IMO some of the reason Europe has pulled ahead in infrastructure and policy is because a couple world wars last century reduced much of it to rubble, including the systems of governance. The UK mostly escaped that, and the US escaped nearly all of it. Which is one reason we can still have a lot of old electrical infrastructure, for example, that is pushing 100 years old, and a Constitutional system 250 years old.
I think a major problem with the system in the US is the difficulty changing it. There is a balance, and a lot of room for differing opinions on how flexible it really ought to be, but I suspect there is broad agreement that it is too inflexible. We rely too much on changing interpretations rather than changing the fundamentals.
Perhaps we really do need to risk a second Constitutional Convention. Or we will end up with a worse alternative.
I could probably go on for another ten pages. Europe definitely has its flaws, but let's not pretend like the US is a paradise where everything is perfect and nothing ever went wrong.
The comparison is stark.
I wish my country had achieved half as much in terms of infrastructure.

I hate it to death. The American government has been an enemy to America, and an enemy to Americans. Since the beginning, with our treatment of the natives.
You'd do well to separate the land, people and government of a nation; confusing them only further serves State propaganda. We force children to say a pledge to our country in school, but it's really to our government. It's political brainwashing. I have refused to say the pledge since becoming politically aware enough around age 7. I cannot tersely express the amount of institutional abuse I suffered for this position. Teachers would ostracize me, bully me, punish me, attempt to physically force me to say it, write me up for detention, get my guardians to abuse me at home over it, etc. Like I said, the American government is a psyop.
I've already discussed how I was personally targeted in my scholastic years as they only person in my schools refusing to participate, so you already knows what happens if you exercise your first amendment rights.

Their own personal judgement about whether something actually helps isn't authoritative, and is usually motivated reasoning anyways.
That probably doesn't seem rational but remember loads of these people think the Bible is a true story.

Those are the (sizeable) subset who are obsessed with a literal interpretation of the Old Testament rather than the turn-the-other-cheek teachings of Christ, who is little more than a totem for these fundamentalists.
Arguably there is less harm in believing that Christ's ministry was historical than believing that Sodom and Gomorrah were historical.
The false equivalence of doing the "both bad!" song and dance serves to so radically under-emphasize the absolute wanton, orders-of-magnitude-worse levels of corruption and evisceration of norms of one side by reducing it to "more bad than the other but they're both very bad." It allows the window to shift to normalize the sort of destruction of systems we're seeing by hand waving away how "the other guys aren't great, either!" It's borderline discourse malpractice at this point, and should be called out as such.
While the right is comfortable holding their nose when white supremacists hang around because it gets them a bigger coalition, the left will excommunicate someone for saying out loud that they think trans women are not exactly equivalent to biological women. This shrinking of the coalition is how we ended up enduring another Trump presidency.
Not to mention the complete fiasco that was the 2024 presidential race. We should have thrown out the entirety of DNC leadership several levels deep for letting that happen.
From an outside perspective the US does not have a political left. The policies proposed by the Democrats are roughly in line with the mainstream right-wing parties in the rest of the world. A mainstream left-wing party would look an awful lot like someone like Bernie Sanders - and we all know the Democrats would rather platform a wet paper towel and lose than see him gain any kind of power!
the density is low though
observe that where Helium becomes a significant percentage, there is also Hydrogen and (monoatomic) Oxygen.
if one were driven by purism or vanity for stoichiometric exactness, then at a height of 1000 km theres 2 Hydrogens per Oxygen atom, so this could be reacted to water, and the energy used to power compression of the Helium, the water would freeze.
without this vanity, helium becomes a significant fraction at much lower heights... and thus higher densities.
The energy to compress becomes nearly insignificant at low pressures.
if humanity ever builds space elevators, this will be one of many benefits of having space elevators.

Oxygen, nitrogen, CO2 and argon make up 99.94% of the atmosphere. The remaining 0.06% has 5ppm is nearly 1% helium. That's up 200x from the original concentration and is well above the 0.3% that is sometimes quoted as the limit for economic extraction of helium (and well below the 7% of some natural gas).
Furthermore, the leftover gas is also already cold. It is absolutely true that 85K isn't very close to the boiling point of helium, it is a lot closer than starting at the temperature of gas at the well head.
The gotcha is almost certainly going to be that an ASU probably doesn't liquify most of the gas it takes in. That means that the exhaust gas will only be slightly enhanced.
GP ain't wrong, but the phrasing implied we'd have it closer by than it actually is.
But, I'm also confident they were making a silly joke.

Awesome graph! Worth stating that the increase in the relative fraction of He isn't so much because there's a lot of He out there as because there's a lot less of everything else. Overall density falls off roughly exponentially but lighter elements have a longer tail.
So once you get out to a few earth radii quite a bit of what you see might be ionized helium but that doesn't mean you can do much with it.

It could be free if we imagine some crazy advances in autonomous self-replicating spacecrafts. But by then we live in the post-scarcity diamond age probably.
Sending the harvest down could maybe happen inside plastic containers built in place, made with the abundant sunlight, some Co2 and water (not sure if there's CO2 this high though. In retrospect we'd need also some metals to print some sort of the antenna reflecting radar frequencies (for the ground stations tracking them on the approach)?
And with the hundreds of small containers (carefully balanced so they don't smash in the ground but slowly rain onto the area) maybe it'd be easier.
I don't know. I think it's hard sci-fi, achievable within our lifetimes :)
The funny part is, lunar regolite soaks Helium from its exposure to solar wind, so mining it would be an indirect mining of a star, our sun.
It would be quite expensive to extract it from there, due to the necessity of escaping from their gravitational field, but not impossible.
There was a dedicated system underground. Vacuum jacketed tubes taking waste helium from the labs to a reservoir across campus.
Helium is rare, helium 3 is precious.
But we can capture more of it from natural gas wells. Today much helium is just vented off and wasted at wellheads. As the price rises it makes sense to invest in cryogenic helium capture equipment for more wells.
Others have mentioned that some helium exists on the Moon, where it comes from the solar wind. The use of the helium 3 from there has been suggested for nuclear fusion, if the fusion of helium 3 became possible (it is much more difficult than the fusion of tritium with deuterium, which is the main approach attempted for now).
However, for fusion relatively small amounts could still be useful. For other uses the amount of lunar helium might not be enough, even when ignoring how expensive it would be to transport it from there.
Similar to oil and gas (although a completely different mechanism), it takes deep time to accumulate, but can be extracted much, much faster. So although new helium is being generated underground all the time, we can still run out in a practical sense.
And lastly we have alpha radiation, which is just a Helium nucleus. A sheet of paper will generally block alpha radiation.
Some materials are really strong alpha emitters. A good example is Polonium-210 where almost all of its energy from decay is in the form of alpha radiation. This is why Po-210 is so lethal when ingested, which has been used for that purpose [1].
But this means if you produce a lump of Polonium-210, it's basically radiating Helium. The source of almost all of the Earth's Helium is from uranium and thorium decay.

They are indeed. The average planet busting Gamma Ray Burst is just a Vogon trying to "get the whole family in".
I agree that the "accumulation over millions of years" is similar (and similarly a potential problem if we burn through all that accumulation).
> These could exist in planets like Neptune or Uranus.

Same with fusion. Due to the implications of E=mc^2, fusion yields a lot of energy and a uselessly-small amount of matter. There don't seem to be many good ways to get a lot of helium besides either waiting millions of years for it to show up naturally, or carefully recycling what we already have.
Water would be the best for this. The cross-section is good and water can ionise easily. But yeah, you would not get a lot of it.
Gas giant atmosphere extraction sounds very far future
When you hear about alpha decay of radioactive materials, that is the matter spitting off a highly ionized helium nucleus, freshly birthed into this world. That He nucleus rapidly steals electrons from matter, which is how it can be dangerous to human cells if ingested.
All of that helium underground is the result of alpha decay, and a single uranium-238 element will birth 8 helium atoms as it transitions through a series of metals and one gas (radon), then finally finding stability as Pb206. U235 will birth 7, becoming Pb207.
Anyways, found that fascinating. It's just happenstance that helium often gets blocked exiting the crust by the same sort of structures that block natural gas from escaping, and they are an odd-couple sharing little in common.
One other fun fact -- radon only has a half life of 3.8 days. Uranium becomes thorium becomes radium, then radon where it has an average 3.8 days to seep out of the Earth and into our basements, where it then becomes radioactive metals that attach to dust, get breathed in (or eaten) and present dangers. In the scale of things, crazy. Chemistry is fascinating.
tfa:
> Thanks to its filled outer electron shell, it is inert, and won’t react with other materials
And by stealing those electrons from other molecules it sets off other chemical reactions, which in things like DNA is highly suboptimal. This all generally happens at the birth of the He atom, presuming it isn't in deep space or something with no electrons to cleave from neighbours, and is only an instantaneous state.
“Because they are identical to helium nuclei, they are also sometimes written as He2+…” [1].

Well, this is part of it. The other issue is that the superconducting phase diagram has two limits: the transition temperature Tc and the upper critical magnetic field Hc. The magnetic field limit is generally highest at absolute zero and drops steeply with temperature. Even for the superconductors with Tc as high as 120 K the Hc at 20 K will be much less than the Hc at 4 K. So in order to make powerful superconducting magnets you need helium regardless of what superconductor you use, since nothing has broken this pattern.
10-20 years ago there was a lot of talk about how this was foolish because it was depleting and squandering an unrenewable resource. But the thinking has shifted on that because it's an inevitable byproduct of natural gas production.
Now natural gas itself is limited but you can still get Helium from alpha decay of radioactive elements. Some elements are particularly strong alpha emitters (eg Polonium-210, Radium-223). They're basiclaly producing Helium constantly.
Helium is a known issue in various industries. The article notes (correctly) that MRI Helium use is decreasing because of the rise of so-called "Helium free" or "Helium light" MRI technology.
But there are short term supply issues. As noted, Qatar produces ~30% of the world's Helium currently. And that can (and has) been disrupted by recent events.
Lithography is a particularly important consumer of Helium for superconducting magnets. That demand is rising with probably no end in sight. Lithography itself is on the cutting edge of technology and engineering so seems harder to replace. I mean, EUV lithography is basically magic.

But instead of our grandparents and great grandparents general idea of investing in the future of their societies, we’ve decided to stop doing that and add up all the debt possible to pass down to future generations.
It is quite depressing to think about.
This is even true at a genetic level, the human genome is rich in fitness, but with healthcare we are lifting natural selection pressure and feasting on the fitness we inherited as if it can be taken for granted, at the cost of future generations genetic fitness.
But for some reason for Americans peace is never the preferred option.

Could be:
"The war in Iran" should be called what it is:
It's 'Trump's War', and nothing else. He's solely to blame. Israel would not have started it on their own.
The kicker is that MAGA voted for the 'no-war' president, and so far, he's started five.
Note that in addition to spelling and grammar, I switched "FIVE" to lower-case italics (which are reverted to regular because the block is italicized), as capitalizing for emphasis is against the HN guidelines.
